how to cancel subscription

I was just wondering how do I go about canceling my professional subscribtion of the ccleaner I had a problem with my debit card and talk to my bank and now its been canceled and I have to wait 7 to 10 business day before I get a new one and I don't want Ccleaner to be out of the money that I paid for it that's why I need to cancel my subscription cause my card won't work thanks in advance if you can help me cancel it

It would be best to contact ccleaner directly either by email

support@ccleaner.com

or via the web link
